Came from a well-connected family: a former Lord Mayor of London was her grandfather, her brother was a field marshall. Already separated from her Irish Catholic MP husband, she had a long-standing relationship with Charles Stewart Parnell throughout the 1880s, which eventually led to a scandalous divorce case in 1889. She married Parnell at Steyning in the year of his death. She is buried at Littlehampton.
